Station Tuning
Select desired band by pushing the

tuned in by turning the manual tuning
knob (4). For good reception, accu­
rate manual tuning is important.
To preset stations of various wave

FM Reception
FM signals travel in a " line-of-sight".
Reflections or " dead spots'' may
cause cancellations or loss of the
signal as well as strong signal
overloading or capture.
Lowering the antenna height in strong
signal areas may eliminate many of
the resulting problems and restore
clarity. However, fringe area reception
requires the antenna fully extended to
receive weak incoming signals. The
antenna can be operated by depress­
ing the respective side of the rocker
switch.

FM Stereo Reception
If an FM stereo station is tuned in the
red Stereo Indicator Lamp will come
on. Good quality stereo reception,
however, is possible only in areas of
high field intensity.
Accurate tuning to the strongest
available stereo stations is of particu­
lar importance for fringe area recep­
tion.
Your radio is fitted with a continuously
operating Stereo Decoder which
automatically switches the radio from
stereo to mono reception if the signal
becomes too weak. The Stereo
Indicator Lamp remains lit. If the
signals of the station tuned in
become too weak, the Stereo Indica­
tor Lamp goes out.
The radio will return to stereo mode
automatically when signal strength
permits.
Tape Playback
Insert cassette (side 1 pointing up­
wards) into cassette slot and push in
to the stop. The radio will then switch
over from radio reception to tape
playback.
If one side of the tape is finished the
player changes over to the other side
of the tape automatically (continuous
operation).
If tape sides are to be changed while
playing, push track changeover but­
ton (10).
Track indicator (9) indicates the tape
side being played.
